Voyager 1 is the first spacecraft to reach interstellar space. It originally was launched (along with Voyager 2) in 1977 to explore the outer planets in our solar system. However, it has remained operational long past expectations and continues to send information about its journeys back to Earth.

The spacecraft officially entered interstellar space in August 2012, almost 35 years after its voyage began. The discovery wasn't made official until 2013, however, when scientists had time to review the data sent back from Voyager 1.

Voyager 1 was actually the second of the twin spacecraft to launch, but it was the first to race by Jupiter and Saturn. The images it sent back have been used in schoolbooks and newspaper outlets for a generation. Also on board was a special record, carrying voices and music from Earth out into the cosmos.

Voyager 2 launched on Aug. 20, 1977, and Voyager 1 launched about two weeks later, on Sept. 5. Since then, the spacecraft have been traveling along different flight paths and at different speeds. The Voyager missions were intended to take advantage of a special alignment of the outer planets that happens every 176 years. It would allow a spacecraft to slingshot from one planet to the next, assisted by the first planet's gravity.

The spacecraft’s next big encounter will take place in 40,000 years, when Voyager 1 comes within 1.7 light-years of the star AC +79 3888. (The star itself is roughly 17.5 light-years from Earth.) However, Voyager 1's falling power supply means it will stop transmitting data by about 2025, meaning no data will flow back from that distant location.

Recognizing that the Voyagers would fly out of the solar system, NASA authorized the production of two records to be placed on board the spacecraft. Sounds ranging from whale calls to the music of Chuck Berry were placed on board, as well as spoken greetings in 55 languages.

The 12-inch, gold-plated copper disks also included pictorials showing how to operate it, and the position of the sun among nearby pulsars in case extraterrestrials were wondering where the spacecraft came from.
Eye on Jupiter

Voyager 1 almost didn't get off the ground at its launch, as its rocket came within 3.5 seconds of running out of fuel on Sept. 5, 1977.

But it made it safely, and raced past its twin after launch, leaving the asteroid belt before Voyager 2 did. Voyager 1's first pictures of Jupiter beamed back to Earth in April 1978, when it was 165 million miles away.

To NASA's surprise, in March 1979 Voyager 1 spotted a thin ring circling the planet. It found two new moons as well – Thebe and Metis. Additionally, Voyager 1 sent back detailed pictures of the Galilean moons (Io, Europa, Ganymede and Callisto) as well as Amalthea.

Like the Pioneer spacecraft before it, Voyager's look at Jupiter's moons revealed them to be active worlds of their own. Voyager 1 came out with some intriguing findings, as well. Io's volcanoes and mottled yellow-brown-orange surface were intriguing finds, proving that, like planets, moons could have active interiors.

Additionally, Voyager 1 sent back ephemeral pictures of Europa showing a smooth surface broken up by lines, hinting at ice and maybe even an ocean underneath.

Voyager 1's closest approach to Jupiter was on March 5, 1979, when it came within 174,000 miles of the turbulent cloud tops. Then it was time to aim for Saturn.
